    Hello Tobii team,

    I am studying tobii document “Accuracy and precision test method for remote eye trackers 2011”.

    Appendix 1 – Accuracy calculations mentioned equation:

    Angle AccuracyRight = (PixelSize*PixelAccuracyRight*cos(AngleRight)^2)/DistanceRight

    I don’t know how the cos(AngleRight)^2 formula is calculated.

    Would you explain what does it mean ? And explain the Angle Acuuracy calculation process.

    Thank you very much !
